Aspects of the present disclosure may include a method and/or a system for applying, to one or more surface electrode trapped ions, a first electric field in a first direction, applying, to the one or more surface electrode trapped ions, a plurality of second electric fields in a second direction while applying the first electric field, wherein the second direction is substantially orthogonal to the first direction, measuring, for each of the plurality of second electric fields, a corresponding micromotion signal associated with the application of one or more of the first electric field or one of the plurality of second electric fields, identifying a maximum micromotion signal of a plurality of micromotion signals associated with the plurality of second electric fields, and identifying a compensation field associated with the maximum micromotion signal.

Methods and apparatuses for stray field compensation normal to a surface electrode ion trap

A method and system is provided for operating a quantum information processing (QIP) system, including a dual-space, single-species architecture for trapped-ion quantum information processing. An exemplary method of preparing the ions include i) applying a first optical beam to the plurality of ions to shelve at least a portion of the plurality of ions from a first state to a second state, ii) applying a second optical beam to the plurality of ions to deshelve the at least a portion of the plurality of ions from the second state to a third state, iii) applying a third optical beam to optically pump the at least a portion of the plurality of ions from the third state and to a fourth state, and iv) iteratively repeat i) to iii) to transition a remaining portion of the plurality of ions to the fourth state.

Methods and apparatuses for barium states preparations for quantum operations

Aspects of the present disclosure may include a method and/or a system for identifying an ion chain having a plurality of trapped ions, selecting at least two non-consecutive trapped ions in the ion chain for implementing a qubit, applying at least a first Raman beam to shuttle at least one neighbor ion of the at least two non-consecutive trapped ions from a ground state to a metastable state, and applying at least a second Raman beam to one or more of the at least two non-consecutive trapped ions, after shuttling the at least one neighbor ion to the metastable state, to transition from a first manifold to a second manifold.
